Example #1 TokyoTyrantIterator::__construct() example

<?php
/* Connect to a table database */
$tt = new TokyoTyrantTable("localhost", 1979);
/* Passing null to put generates a new uid */
$index = $tt->put(null, array("column1" => "some data", "column2" => "more data"));
/* Construct an iterator */
$it = new TokyoTyrantIterator($tt);
foreach ($it as $value) {
    var_dump($value);

array(2) {
  ["column1"]=>
  string(9) "some data"
